What Causes Green Tea Side Effects?

By Anna Burns

TV shows and health periodicals have been advertising green tea extract as an excellent supplement for fat loss. With the raising interest of tea, a lot of people are questioning the safeness of the supplement. A lot of the media supporting the benefits of tea are usually not identifying enough of the unwanted effects. Fully knowing the possible side effects is crucial in order to take health benefits with no harmful outcomes.

Much like many dietary supplements or prescription drugs, the amount has an important role with regards to side effects. If consumed without care, even the most healthy supplement results in unanticipated effects. Identical reasoning is true here. Exactly what is the right amount of tea?

The most active substances of tea are catechin and caffeine. Both assist with making use of fat as the supply to make energy which is called thermogenesis. This process in return raises metabolism. Accelerated metabolism burns fat quicker in the human body.

There were a lot of experiments on caffeine and how it impacts human body. Many health specialists are stating typically beyond 500mg of caffeine per day is too much. It could be harmful resulting in side effects like insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Industry experts also acknowledge that level of responsiveness to caffeine varies by an individual, however 300mg or lower is considered a risk-free dose.

In a single cup of tea, one can find approximately 20mg of caffeine. Compare to other caffeinated drinks, it is a small amount. In a single cup of coffee there are approximately 100mg of caffeine. When tea is the only caffeinated beverage consumed then it should not be an issue. But if additional caffeinated beverages are consumed during the day, then it is important to check the entire daily amount of caffeine.

Tea researchers conducted lab tests related to the amount of tea. A daily amount of 800mg of EGCG was tested with success and without unwanted side effects. A single cup of tea comes with approximately 100mg of EGCG, which is 8 cups of green tea. Most laboratory tests claim more EGCG equals to more fat reduction, however some medical experts agree that large quantity of isolated compound from herbal plants may be a problem. It is challenging to make a definite conclusion based on lab tests, still numerous researchers are saying 300mg of EGCG is a safe dose to take in a day. There have been successful scientific reports while using the dosage of 300mg fighting cancer cells and weight reduction.

Because of the growing popularity of green tea, much more laboratory tests will likely be done. For the time being, 300mg appears to be an ideal dosage for both EGCG and caffeine.
